The company raised a $300 million Series B extension in March 2026 led by Full Vision Capital, bringing total funding to $445 million. EnerVenue's batteries are lithium-free and rated for 30,000 charge cycles — roughly 10x the lifespan of standard lithium-ion systems — making them purpose-built for demanding grid-scale and data center applications. The company's timing is particularly strong: AI data center buildout is creating unprecedented demand for reliable, long-cycle energy storage, and lithium supply chain concerns have intensified interest in alternative chemistries. EnerVenue's NASA heritage gives its technology a provable track record in the harshest operating conditions — satellites run continuously for decades without maintenance — translating directly to grid reliability requirements. EnerVenue is manufacturing scale-up in 2026, deploying its batteries in utility and commercial projects. The company is targeting both traditional grid storage markets (peak shaving, renewable firming) and the emerging AI data center backup power segment, where energy density and cycle life are less critical than absolute reliability and operational longevity. ## Frequently Asked Questions ### What does EnerVenue make? Nickel-hydrogen batteries for grid-scale energy storage — lithium-free, 30,000-cycle lifespan, based on NASA satellite battery technology. ### How much has EnerVenue raised? $300M Series B extension in March 2026 led by Full Vision Capital. $445M total raised. ### Why nickel-hydrogen instead of lithium-ion? 10x longer cycle life (30,000 vs ~3,000 cycles), no lithium supply chain dependency, and proven reliability from decades of NASA satellite deployments. ### What markets is EnerVenue targeting? Utility grid storage, renewable energy firming, and AI data center backup power — where reliability and longevity outweigh raw energy density. ### What chemistry does EnerVenue use for grid-scale storage? EnerVenue uses nickel-hydrogen battery chemistry — originally developed for NASA satellites and the International Space Station — adapted for terrestrial grid storage. The chemistry is known for extreme cycle life (30,000+ cycles), wide temperature tolerance, and no thermal runaway risk. ### How does EnerVenue's cycle life compare to lithium-ion? EnerVenue batteries are rated for 30,000+ full charge-discharge cycles with minimal capacity degradation — compared to 3,000-6,000 cycles for lithium-iron phosphate (LFP) batteries. This lifetime advantage makes the total cost of storage highly competitive over a 20-30 year project life. ### What are EnerVenue's target applications? EnerVenue targets utility-scale long-duration energy storage (8-24 hour discharge), commercial and industrial behind-the-meter storage, and microgrids in remote or harsh-environment applications where lithium-ion batteries struggle with temperature extremes or safety requirements. ### Where is EnerVenue manufacturing its batteries? EnerVenue is building manufacturing capacity in Turlock, California — its Giga America facility — with plans to produce gigawatt-hours of nickel-hydrogen storage annually to serve utility and commercial customers in the US. ## Tags energy, b2b --- *Data from geo.sig.ai Brand Intelligence Database.
